Guided Bone Regeneration (GBR)

Where Does the Bone Come From?

The bone used during Guided Bone Regeneration does not usually come from another area of your own jaw. In most cases, dentists use highly processed bone graft materials that serve as a scaffold for your body’s natural healing process. These grafts may be derived from donated human bone (allograft), purified animal bone (xenograft), or synthetic materials (Alloplast). Each material has been extensively studied and is carefully processed to meet strict safety and quality standards.

Over time, your body’s own bone cells gradually grow into the graft and replace much of the material with new living bone, creating a strong and stable foundation for dental implants or other restorative procedures. The choice of graft material depends on the size and location of the defect, your overall health and your surgeon’s clinical judgment.

How Does Guided Bone Regeneration Work?

The success of Guided Bone Regeneration depends on controlling how different tissues heal. Gum tissue naturally grows much faster than bone. Without a barrier, the gum tissue would occupy the space before new bone has an opportunity to develop.

To prevent this, a thin membrane is placed over the bone graft. The membrane protects the graft, stabilizes the healing area and creates a secluded space where bone cells can regenerate. This process allows the slower-growing bone to fill the defect while keeping unwanted soft tissue out of the area.

Once healing is complete, the regenerated bone becomes integrated with the surrounding jawbone and is capable of supporting a dental implant.

How Is Guided Bone Regeneration Performed?

The procedure is performed under local anesthesia to ensure your comfort. After carefully exposing the treatment area, your surgeon places bone graft material into the area where additional bone is needed. A specialized resorbable or non-resorbable membrane is then secured over the graft to protect it during healing and maintain the necessary space for new bone formation. The gum tissue is repositioned and sutured closed to allow the area to heal undisturbed.

Depending on the amount of bone loss, Guided Bone Regeneration may be performed at the same time as dental implant placement or several months beforehand when more extensive bone reconstruction is required.

Healing After Guided Bone Regeneration

Healing occurs gradually as your body replaces the graft material with newly formed bone. Most patients experience only mild swelling and soreness for several days, which can usually be managed with prescribed or over-the-counter medications. You should avoid chewing directly on the treated area during the early stages of healing and carefully follow all postoperative instructions to protect the graft.

Bone maturation generally requires several months before the site is ready for implant placement or final restoration. Regular follow-up appointments allow your surgeon to monitor healing and ensure the graft is developing properly.
